1. An onboard charging apparatus comprising:
a first noise filter that is coupled to a connector, the connector being configured to couple a direct-current power source to a battery through a charge line, wherein the first noise filter reduces noise;
a second noise filter that is coupled to an AC/DC converter that converts alternating-current power supplied from an alternating-current power source to a direct-current power, the second noise filter being operative to reduce noise; and
a relay that is disposed between the first noise filter and the battery,
wherein the relay switches off current flowing in the charge line when the battery is not electrically coupled to the direct-current power source.
